The storage market needs a shift; proprietary storage systems are incapable of providing future data storage needs at a relatively low budget. After hardware procurement, licensing, support, and management costs, the proprietary systems are very expensive. In contrast to this, the open source storage technologies are well proven for their performance, reliability, scalability, and lower TCO. Numerous organizations, government-owned as well as private, universities, research and healthcare centers, and HPC systems are already using some kind of open source storage solution.

However, Ceph is getting tremendous feedback and gaining popularity, leaving other open source as well as proprietary storage solutions behind. The following are some open source storage solutions in competition with Ceph. We will briefly discuss the shortcomings of these storage solutions, which have been addressed in Ceph.
